The advent of elegant theories, such as special relativity and quantum mechanics, ushered modern physics into an era marked by fantasized contemplation of phenomena, a trend that even persists today. In principle, every phenomenon is physical and can be comprehended mechanistically, given access to the necessary information. In a previous study, we explored the discussion on the equivalence of quantum mechanics with Fick's second law as its classical analogous for Brownian particles which reveals that there should be underlying particles that govern the motion of subatomic particles in quantum mechanics. In this context, we delve into how the description of a special aether medium in space enables the system to adhere to Galilean relativity instead of special relativity, which assumes the absence of aether. Given this, we emphasize that space and time are absolute; rather, it is indeed the velocity that is relative to the initial frame of reference.
